A method for producing oxidative-organosolvent pulp, in which technically prepared plant chaff is loaded into a cooking apparatus, poured with a cooking solution at a hydraulic module of 10:1, which includes water, hydrogen peroxide, organic acid and a catalyst, and cooked. Ice-cold acetic acid is used as the organic acid in the cooking solution. The ratio of acid to water is 75:25 by volume. Hydrogen peroxide is added to the cooking solution in an amount of 50 % by weight of absolutely dry raw materials. As a catalyst, add citric acid in an amount of 0.5 % by weight of absolutely dry raw materials. Cook at a temperature of 90 ± 5 °C for 60 ± 3 to 120 ± 3 minutes, followed by grinding the mass in a centrifugal grinding machine.
The utility model belongs to the field of pulp and paper industry, in particular to methods for obtaining cellulose from vegetable agricultural waste and non-wood plant raw materials, which can be used, for example, for the production of paper and cellulose membranes.
